    Abstract: A pressure sensor (15) with double measuring scale, comprising: a flexible body (16, 34) designed to undergo deflection as a function of a said pressure (P); piezoresistive transducers (28, 29; 94) for detecting the deflection; a first focusing region (30) designed to concentrate, during a first operating condition, a first value (P INT1 ) of said pressure (P) in a first portion (19) of the flexible body (16, 34) so as to generate a deflection of the first portion (19) of the flexible body (16, 34); and a second focusing region (33) designed to concentrate, during a second operating condition, a second value (P INT2 ) of said pressure (P) in a second portion (17) of the flexible body (16, 34) so as to generate a deflection of the second portion (17) of the flexible body (16, 34). The piezoresistive transducers correlate the deflection of the first portion (19) of the flexible body (16, 34) to the first pressure value (P INT1 ) and the deflection of the second portion (17) of the flexible body (16, 34) to the second pressure value (P INT2 ).

    Abstract translation: 的压力传感器（15）与双测量刻度，包括：柔性体（16，34）设计成经历偏转为所述压力（P）的函数; 压阻换能器（28，29; 94），用于检测所述偏转; 设计为浓缩物，在第一操作条件期间的第一聚焦区（30），在所述柔性主体（16，34）的第一部分（19）的第一值，所述压力的（P INT1）（P），以便产生 柔性主体（16，34）的第一部分（19）的偏转; 并设计成集中，第二操作条件期间的第二聚焦区（33），第二个值的所述压力的（P INT2）（P）在所述柔性主体的第二部分（17）（16，34），以便 生成柔性主体（16，34）的第二部分（17）的偏转。 压阻传感器的柔性主体（16，34）的第一压力值（P INT1）和柔性主体的第二部分（17）的偏转的第一部分（19）的偏转相关（16，34） 到第二压力值（P INT2）。
